Overview
|
The first significant winter storm of the 2024-2025 snow season brought a widespread 2" to 6" of snow with higher amounts from 6" to 8" in spots. As the initial band of snow moved from west to east early Thursday morning locations in southeast Minnesota reported 1" to 3" by the morning commute. This initial snowfall reached the Mississippi River Valley just in time for the morning commute creating slippery to hazardous travel conditions. Overall initial accumulations of 1" to 4" were reported through the morning commute. As the initial bands of snowfall tightened through the late morning during the late morning and afternoon, heavier snowfall bands set up near the Interstate 90 corridor. Another band of snow set up from southeast Minnesota into southwest Wisconsin later in the afternoon and evening, along with patchy freezing drizzle. Overnight, another 1/2" of snow fell across the area. |
